The novel coronavirus, now termed SARS-CoV-2, has caused a significant global impact in the space of 4 months. Almost all elective cardiac surgical operations have been postponed in order to reduce transmission and to allocate resources adequately. Urgent and emergency cardiac surgery is still taking place during the pandemic. The decision to operate in urgent patients with active/recent COVID-19 infection is difficult to make, particularly as it is still an unknown disease entity in the setting of emergent cardiac surgery. We present a case series of three patients who underwent urgent cardiac surgery and who have had recent or active COVID-19 infection.Background and aim It has been demonstrated that patients with pre-frailty have more adverse outcomes after cardiac surgery; however, data on prognosis and long-term evolution in patients with pre-frailty after elective cardiac surgery without postoperative complications are still scarce. To evaluate the impact of pre-frailty status on functional survival in patients after elective cardiac surgery without surgical complications. Methods This was a retrospective study with 141 patients over 65 years old, with an established diagnosis of myocardial infarction or valve disease. Patients were evaluated by Clinical Frailty Scale (CFS) before surgery, according to the hospital protocol, and allocated into two groups non-frail (CFS, 1-3) and pre-frail (CFS = 4). Patients with adverse cardiovascular events during surgery or at intensive care unit (ICU), mechanical ventilation more than 24 hours, ICU length of stay more than 48 hours, and in-hospital complications were excluded. For all analyses, the statistical significance was set at 5% (P less then .05). Results There were no differences in demographic, anthropometric, surgical procedure, or baseline data on ICU. Pre-frail patients had more adverse events during the 3-year follow-up period with rehospitalization compared to non-frail (39.4% vs 14.3%, respectively). Rehospitalizations in pre-frail patients were in the first year after cardiac surgery (P less then .05), and higher cumulative events in pre-frail have occurred with increased odds ratio (OR) (2.828, 95% confidence interval [CI] 1.298-6.160; P = .001) and hazard ratio (HR) (3.560, 95% CI 1.508-84.04; P = .004). The OR and HR for stroke or death were similar between groups when analyzed separately. Conclusion Pre-frail patients have more adverse events after elective cardiac surgery without complications when compared to non-frail patients.We received a response to our Editorial from a group in Brazil that raised valuable concerns about the struggles in transforming medical education in low-income countries. Here, we address the concerns they raised that reinforce the global need for a "Coalition for Medical Education."Transplant glomerulopathy (TG) is a major cause of late allograft loss. Increased urine podocin/creatinine ratio in TG signifies accelerated podocyte loss. The mechanisms that lead to podocyte injury in TG remain unclear. We report that IgG from kidney transplant recipients with TG, but not from those without TG, cause a reduction in the expression of nephrin, significant podocyte actin cytoskeleton and motility changes. https://www.selleckchem.com/products/mki-1.html These changes are preceded by increased expression of calcium/calmodulin kinase IV (CAMK4). Mechanistically, we found that CAMK4 phosphorylates GSK3β, activates the Wnt pathway and stabilizes the nephrin transcriptional repressor SNAIL. Silencing neonatal Fc Receptor (FcRn) or CAMK4 prevented the podocyte-damaging effects of IgG from patients with TG. Furthermore, we show that removal of N-linked glycosyl residues from these IgG did not interfere with its entry into the podocytes but eliminated its ability to upregulate CAMK4 and cause podocyte injury. The translational value of these findings is signified by the fact that CAMK4 is increased in podocytes of patients with TG but not in those without TG despite other forms of renal dysfunction. Our results offer novel considerations to limit podocyte injury in patients with kidney transplants which may lead to eventual glomerular destabilization and transplant glomerulopathy.We read with great interest the article by Piccolo et al1 . describing chilblain-like lesions (CLL) on feet and hands during the COVID-19 Pandemic. They mention the rate of association to autoimmune conditions was very low, which led the to exclude a note autoimmune disorder as main cause of CLL. Here, we hypothesize the possible relationship between the development of these lesions and immune-chained phenomena following viral infection in a certain group of patients.A 59‐year‐old man was admitted to hospital for a severe respiratory failure and then intubated due to worsening of his respiratory condition. During his hospital stay, he received multiple empirical broad spectrum antibiotics (cefepime, piperacillin/tazobactam, linezolid, gentamicin and meropenem plus amikacin). The patient had no known history of drug allergies. A test to detect SARS‐CoV‐2 by real‐time reverse‐transcription‐polymerase‐chain‐reaction (RT‐PCR) assay of a throat swab was positive. Blood cell count showed severe eosinophilia (from 1,3 to 4.60 x 10) that decreased abruptly to 0.47 x 10 after introduction of methylprednisolone 1 mg/kg/day. On day 35 post admission, while on therapy only with corticosteroids, he developed a symmetrically distributed maculopapular purpuric exanthema on the face, trunk and extremities (Fig.1 a,b). Mucous membranes were spared.Oxidative stress (OS) is an in-vivo process leading to free radical overproduction, which triggers polyunsaturated fatty acid (PUFA) peroxidation resulting in the formation of racemic non-enzymatic oxygenated metabolites. As potential biomarkers of OS, their in-vivo quantification is of great interest. However, since a large number of isomeric metabolites is formed in parallel, their quantification remains difficult without primary standards. Three new PUFA-metabolites, namely 18-F 3t -Isoprostane (IsoP) from eicosapentaenoic acid (EPA), 20-F 4t -Neuroprostane (NeuroP) from docosahexaenoic acid (DHA) and 20-F 3t -NeuroP from docosapentaenoic acid (DPA n-3 ) were synthesized by two complementary synthetic strategies. The first one relied on a racemic approach to 18( RS )-18-F 3t -IsoP using an oxidative radical anion cyclization as a key step, whereas the second used an enzymatic deracemization of a bicyclo[3.3.0]octene intermediate obtained from cyclooctadiene to pursue an asymmetric synthesis. The synthesized metabolites were applied in targeted lipidomics to prove lipid peroxidation in edible oils of commercial nutraceuticals.
